Acar is initially driving at 30 m/s. it hits a large pothole, after which it is traveling in the same direction but at 25 m/s. draw vectors representing the initial velocity final velocity, and (hange in velocity which describe the equation : + δ¡. 2. the si nit for weight is the newton (not the express the weight of a 2.8 lbs. watermelon in newtons. 3. on mars gravitational acceleration is amars 3.71 m/s2 or amars 0.37g, where g is the gravitational acceleration of on object on earth. if a future astronaut drops a rock from a height of 1.9 m how long will it take to hit the ground on mars? compare that number to how long the same rock would take to fall on earth.

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
